Please refer to FIGS. 1 to 6, which are schematic view of configuration,a first schematic view, a second schematic view, a third schematic view,a fourth schematic view and a fifth schematic view of a spinning bike ofan embodiment of the present invention, respectively. As shown infigures, the spinning bike includes a bike frame 100, a transmissionwheel 200, a flywheel 300 and a resistance braking device 400.

The transmission wheel 200 is disposed on the bike frame 100. Theflywheel 300 is made of the metal material and driven by thetransmission wheel 200 to rotate. Preferably, the metal material of theflywheel 300 includes aluminum; in another embodiment, the spinning bike10 may include a transmission belt 800 mounted on the flywheel 300 andthe transmission wheel 200, so that the transmission wheel 200 can drivethe flywheel 300 to rotate.

Furthermore, in an embodiment, the spinning bike 10 can include a pedalassembly 600 and a crankset 700. The crankset 700 includes an enddisposed on the transmission wheel 200, and another end connected to thepedal assembly 600, so that a user can step on the pedal assembly 600 todrive the flywheel 300 to rotate. The pedal assembly 600 can include afoot plate to assist the user to step on the pedal assembly 600 moresmoothly without slipping off the pedal assembly 600 easily. In anembodiment, the spinning bike includes the resistance braking device400, so that the resistance of the spinning bike can be adjusted, toassist the user for training.

The resistance braking device 400 includes a resistance adjustmentmember 900, a magnet assembly 401, a control member 404, a manual brakeassembly 402 and a resistance control assembly 403. The resistanceadjustment member 900 is connected to the bike frame 100, and the magnetassembly 401 can be pivotally connected on the resistance adjustmentmember 900. Thus, the magnet assembly 401 is movable in the resistanceadjustment member 900 to change the distance from the magnet assembly401 to the flywheel 300, so as to produce different resistance forces orstop rotation of the flywheel 300.

Furthermore, a spacing distance can be formed between the magnetassembly 401 and the flywheel 300. In an embodiment, the magnet assembly401 can include magnetic components (such as magnets) disposed on twoopposite sides of the flywheel 300. When the spacing distance betweenthe magnet assembly 401 and the flywheel 300 becomes shorter, theelectromagnetic induction area between the magnetic components and theflywheel 300 becomes larger, so that the spacing distance can beadjusted to provide resistance forces with different degrees.

The control member 404 is connected to the magnet assembly 401, forexample, the control member 404 can be fastened on the magnet assembly401. Furthermore, in an embodiment, the control member 404 can berotatably disposed on the magnet assembly 401, and control the rotationof the control member 404 by using elastic force of an elastic device,such as spring. For example, in an embodiment, after the control member404 is rotated, the control member 404 can be back to its formerposition by the elastic force of the elastic device.

The manual brake assembly 402 can be disposed on the handlebar of thebike frame 100, and include a brake handle 4021 and a brake control wire4022. The brake control wire 4022 includes an end connected to the brakehandle 4021, and another end connected to the control member 404. Whenthe brake handle 4021 is pressed, the brake control wire 4022 can movethe control member 404 to pull the magnet assembly 401, so as to changethe spacing distance. In an embodiment, when the flywheel 300 isrotating, and the brake handle 4021 is pressed, the spacing distance canbe shortened to be a braking distance, to form electromagnetic inductionbetween the flywheel 300 and the magnet assembly 401. In this case, themagnet assembly 401 is very close to the flywheel 300, so the magnetassembly 401 and the flywheel 300 can have the maximum electromagneticinduction area therebetween, to produce and apply a braking resistanceforce on the flywheel 300 to stop the flywheel 300 immediately, therebyachieving the manual braking function.

The resistance control assembly 403 can include a motor 4031, a controlinterface 4032 and a resistance control wire 4033. The resistancecontrol wire 4033 has an end connected to the motor 4031 and another endconnected to the control member 404. The control interface 4032 iselectrically connected to the motor 4031, and configured to control themotor 4031 to roll or release the resistance control wire 4033, so as tochange the spacing distance. In an embodiment, the spacing distance isin a range of a minimum resistance length to a maximum resistancelength. Electromagnetic induction can be formed between the flywheel 300and the magnet assembly 401 to produce and apply different resistanceforce, in a range of the resistance force corresponding to the minimumresistance length to the resistance force corresponding to the maximumresistance length, on the flywheel 300. For example, the sixteen-levelresistance adjustment or smooth resistance adjustment can be provided.

In an embodiment, when the motor 4031 rolls the resistance control wire4033, the control member 404 can drive the magnet assembly 401 to moveaway from the flywheel 300, so as to reduce the resistance force appliedon the flywheel 300. When the motor 4031 releases the resistance controlwire 4033, the control member 404 drives the magnet assembly 401 to moveclose to the flywheel 300, to increase the resistance force applied onthe flywheel 300, thereby providing multi-level resistance forceadjustment.

Furthermore, in an embodiment, in order to prevent the brake controlwire 4022 and the resistance control wire 4033 from interfering thecontrol member 404 to make the resistance function or braking functionabnormal, the motor 4031 can enter an idle state when the brake handle4021 is pressed, so that the resistance control wire 4033 does not drivethe magnet assembly 401.

According to above-mentioned contents, in the spinning bike of thepresent invention, the manual brake assembly 402 and the resistancecontrol assembly 403 can be integrated in the resistance braking device400. Ends of the brake control wire 4022 and the resistance control wire4033 are connected to the motor 4031 and the manual brake assembly 402,respectively, and the other ends of the brake control wire 4022 and theresistance control wire 4033 both are connected to the magnet assembly401, so as to control the spacing distance between the magnet assembly401 and the flywheel 300. In an embodiment, when one of the manual brakeassembly 402 or resistance control assembly 403 is operating, the otherof the manual brake assembly 402 and the resistance control assembly 403can enter the idle state, so that the manual brake assembly 402 and theresistance control assembly 403 do not interfere with each other. Thus,the resistance braking device 400 can perform multi-level electricresistance adjustment and the braking function.

In an embodiment, the spinning bike of the present invention can includea display device 500 disposed on the bike frame 100 and configured todisplay the values of the plurality of resistance forces; in anotherembodiment, the control interface 4032 can include a touch panel 4034.Preferably, the display device 500 and the touch panel 4034 areintegrated with each other, to facilitate the user to view data andoperate the spinning bike easily. Furthermore, in an embodiment, thecontrol interface 4032 can include at least one button 4035, so that theuser can adjust the resistance, or power on or off the spinning bike.

Furthermore, in another embodiment, the control interface 4032 canautomatically control the spacing distance between the magnet assembly401 and the flywheel 300, so that the spinning bike of the presentinvention can electrically adjust the resistance to provide the userwith different training plans, for example, the training plan that theresistance is gradually increased, or the training plan that theresistance is increased and decreased alternatively, to meet uservarious requirements including wellness, slimming, mountain climbingtraining or racing training.

In summary, according to technical solution of the present invention,the resistance control wire 4033 can be rolled or released to adjustresistance force, and the manual brake assembly 402 can also performmanual braking function. The resistance control assembly 403 and themanual brake assembly 402 can be integrated in the resistance brakingdevice 400, and the user can use the control interface 4032 to adjustthe resistance force or manually operate the manual brake assembly 402to brake, thereby meeting safety requirement. As a result, in thespinning bike of the present invention can use the resistance brakingdevice 400 to satisfy multi-level resistance adjustment and the brakingfunction, and production cost can be reduced.
